The cpphs package

Cpphs is a re-implementation of the C pre-processor that is both
more compatible with Haskell, and itself written in Haskell so
that it can be distributed with compilers.

This version of the C pre-processor is pretty-much
feature-complete and compatible with traditional (K&R)
pre-processors. Additional features include: a plain-text mode;
an option to unlit literate code files; and an option to turn
off macro-expansion.

Readme for cpphs

Readme for cpphs-1.18.1

This directory contains 'cpphs', a simplified but robust
re-implementation of cpp, the C pre-processor, in Haskell.
TO BUILD
--------
Just use
hmake cpphs [-package base]
or
ghc --make cpphs [-o cpphs] # -o needed for ghc <= 6.4.1 ]
or
runhugs cpphs # or rename the script cpphs.hugs to cpphs
USAGE
-----
cpphs [filename | -Dsym | -Dsym=val | -Ipath]+ [-Ofile]
[ --include=file ]*
[ --nomacro | --noline | --nowarn | --strip | --strip-eol |
--pragma | --text | --hashes | --layout | --unlit |
--linepragma ]*
[ --cpp compatopts ]
For fuller details, see docs/index.html
If you want to use cpphs as a completely drop-in replacement for the
real cpp, that is, to accept the same arguments, and have broadly
the same behaviour in response to them, then use the --cpp compatibility
option.
